To all whom it may concern.

Be it known that I, JOHANNES ROTH, factory owner, German subject, residing at No. 202 Frankenthalerstrasse, Ludwigshafen-onthe-Rhine, Germany, have invented new and useful Improvements in Automatic Tile- Machines, of which the following is a specication.

This invention relates to automatic tile cutters of the kind in which the moving stream.of clay actuates the cutting devices, which to such end are geared to a controlling shaft rotated by a transmission gear that is connected to guide rollers for the stream of clay caused by the latter to revolve.

The invent-ion consists in certain features of novelty which will appear from the following description and be particularly pointed out in the appended claims.

One illustrative embodiment of my invention is represented by way of example in the accompanying drawings wherein:

Figure 1 is a longitudinal section through the carriage and through apart of the main frame of the machine, Fig. 2 a vertical section taken on the line A-B in Fig. 1 as seen in the direction of the issuing stream of clay, and Fig. 3 a vertical section taken on the line C-D in Fig. l, also as seen in the direction of the forward movement of the stream of clay, while Fig. 4 is a side elevation showing part of the locking mechanism for the lug-cutter, and Fig. 5 is a diagrammatic side elevation of the belt gearing driving the control spindle, Fig. 6 a plan of the machine, Fig. 7 an enlarged detail view more fully described hereafter, Fig. 8 a perspective detail view of a cam referred to later on.

Referring to the drawing, the stream of clay 1, issuing in the direction of the arrow shown in Fig. 1 from the die or mold, first arrives in a well-known manner on the driving rolls 3, which are thereby set in rotation, and then on the smaller guide rolls 60, of which some are journaled in the stationary frame 1 of the machine and others in the well-known carriage 61 running on rails 62. The carriage 61 carries the requisite cutting, punching and marking devices, hereinafter described, driven in common by 7b adjustable on this frame.

the driving shaft 11, which in a well-known manner is connected by a friction clutch 12 to a counter shaft (not shown).

As shown in Figs. 2zand 5, the belt pulleys 4, driving a control spindle 2 by means of the belt pullev 5 on one end thereof and a belt 4a or the like, are fast on the outside projecting ends of the shafts 3 of the two driving rollers 3. The other end of the control spindle 2 has secured on it a cam 6 (Figs. 7 and 8) whose beveled face 6a coacts once during each revolution of the control spindle with a lever 7 in such a manner that this lever is rocked inwardly against the action of a spring 8 around its pivot 7 a, journaled in a bracket on the machine frame 1, and its upper end lifted from an abutment While the machine is working the bottom end of the lever 7 rests alternately against one of two rectilinear, radial .faces 9 of a cam 10 keyed on the shaft 11. For the purpose of driving the cut-ting devices the shaft 11 also has secured fast on it a crank 13 whose pin, carrying an antifriction roller 14, is movable in a slot 15 in the two-armed lever 16. The latter is fulcrumed on the pivot 16.a in a bracket 16" attached to the frame 1 and carries at its top end a pin 17, provided with an antifriction roller 18, movable in a slot 19 in the slide-frame 20 which is guided in the upright frame 21 of the carriage 61 and arranged to operate the cutting devices, as will be described hereafter. To such end, as shown in Figs. 2 and 6, the top and the bottom sliding rod of the frame 20 are each formed as a toothed rack 63, in which a spur wheel 64, fast on a pivot 65 journaled in the frame 21, meshes. With each pivot 65 a sleeve 66 is connected that carries two arms 67, while on each arm 67 a sleeve 68 is adapted to slide. The sleeves 68 carry the pattern-cutting wire 69 stretched between them, as will be seen from Fig. 2. The two upper and the two lower sleeves 68 are respectively connected togetherv by a pin carrying a roller 70 engaging in the upper or the lower, respectively, of the guides 72 which in a well-known manner are interchangeably connected with the frame 21. According in each instance as the guides 72 have the shape of a pointed arch, are circular, segmental, hexagonal or rhomboidal, an exactly similarly shaped front face of the tile will be obtained.

For the purpose of imparting the movement ofthe frame 20 to the cutter which is to produce the straight back face of the tiles and for actuating by means of the same frame also certain punchingv and marking devices, more fully referred to hereafter, the top rod of the frame is provided with a slotted guide 26 engaged by an antifriction roller 25 of an arm 24 fast on a shaft 23 which extends longitudinally of the machine and is journaled in two brackets 22. One of the latter is attached to the frame 21 of the carriage 61 and the other to a like frame 21a thereof.

As shown in Figs. 1 and 3, the straight cutter consists of a bow 37, fixed on the shaft 23, and t-he cutting wire 38, stretched between the ends of such bow. The bow 37 is adjustable along the shaft 23, in order that different lengths of tile can be cut. The shaft 23 carries fast on it a lever 27, -provided with an antifriction 'roller 28, that engages in the slot 29 of a guide piece 30 (Figs. 1 and This slot is shaped so that the motion of the lever 27 causes the guide piece to reciprocate in vertical direction. The guide piece 30 has a vertical forked arm 31 which clasps the boss of the lever 27. The bottom ends of the guide piece 30 are rigid with a bow 0r stirrup 32 which is pivotally attached to the free ends of arms 33 fast on a transverse shaft 34, mounted in the frame 21a of the carriage 61 and which carries two punches 35 fo-r making the nail holes and the stamp 36 for impressing the mark of the firm. The stamp 36 ispreferably guided by a centrally-arranged pin'36 slidable in an eye 36 of the frame 21a of the carriage 61. Y

The well-known lug-cutter 48, the cutting wire of which is designated by 50, is operated by the following means. The shaft 34 is tted with a clutch-coupling, of which one member, 39, is fast thereon, whereas the other, 40, is loose on it and prevented from being displaced longitudinally axially, the member 40 has an arm 41, whose free end is pivotally connected by a rod 42 with an arm 43 of a countershaft 44 likewise mounted in the frame 21a. This shaft has fast on it two levers 45, to whose free ends a bow or stirrup 46 having a pin 47 guided in a sleeve 51 attached to the carriage 61 is pivotally connected. On this pin the lugcutter 48 is mounted which comprises an antifriction roller 49 and the cutting wire 50 and is secured in its elevated or operative position by an elastic catch 53 engaging an arm 52 of the shaft 44 in the manner Y represented in Fig. 4. The catch 53 is at in this manner until on the motion of the carriage 61 a projection 53 of the catch 53 strikes against an adjustable stop 54 on the main frame, the catch thus becoming bent back so that it releases the arm 52, whereupon the lug-cutter can return under the influence of its own weight into its normal position. The lug-cutter is able to fall back in this manner owing, on the one hand, to the clutch member 40 being mounted only loosely on the shaft 34, and, on the other hand, to the clutch member 39 being returned alone into its normal position, when the cutters 69 and 38 are returned into their normal positions, so that a gap permitting the parts designated by the numerals 40 to 52 inclusive to fall back at the proper moment is formed between the clutch members. Consequently, the adjustment and position of the stop 54 on the main frame determine not only the time when the lugcutter descends, but also the length of the lug left on the stream of clay.

As mentioned above, the driven pulley 5 of the control spindle has to be selected corresponding to the length of tile; the smaller its periphery is, the more rapidly will the cutting operations follow one another. But in order that theshaft 2 may always be certainly Y driven when the belt pulley 5 is changed, I provide, in addition, on adjustable idler 55 'for the belt 4a (Fig. 5).

The carriage 61 derives its motion from the spindle 2 by the following arrangement. The carriage 61 has an arm 61a to which a rod 78, pivotally connected by means of links 76 to the stationary frame 77, and a rod 81 are jointedly attached. The rod 78 is under the action of a pin 74 projecting from a disk 73 mounted on the spindle 2. This pin serves to move the carriage in the direction of the arrowshown in Fig. 1. The rod 81 is pivotally connected with a lever 80 that is carried by the frame 77 and provided with a roller 79 adapted to be acted upon by a cam 75 rigid with t-he disk 73. This cam is designed to move the carriage 'in opposite direction to the said arrow.

Y From the foregoing description it will be understood that the action of the tile cutter briefly is as follows: The moving stream of clay rotates the rolls 3 and thus also by means of the pulleys 4 and 5 the spindle 2. On each revolution of the latter the lever 7 is by the cam 6 moved against the action of the spring 8 so as to release the cam 10 mounted on the driving shaft 11. This is now rotated by the friction coupling 12 until after a half-revolution the second surface 9 is engaged by the lever 7. On the rotation of the shaft 11 the lever 16 is moved on its pin 16a so as to displace the frame 2O transversely. The motion of this frame causes the sleevesv66 together with the arms 67 to turn on the pins 65 so thatv the rollers 70 slide in their guides 72, the sleeves 68 moving along the arms 67 in accordance with the shape of the guides 72. In this way the pattern-cutting wire 69 kis caused to act, the form of cut produced depending upon the shape of the interchangeable guides 72. By the gearing 24, 25, 26 the shaft 23 is rotated on the displacement of-the frame 20, and by means of the gearing 27, 28, 30, 33 the rotation of the shaft 23 causes the shaft 34 to turn so that by the gearing 39 to 45 the lug cutter 48 is raised into its operative position. On this operation the rotation of the shaft 44 brings about the engagement of the arm 52 with the. catch 53 so as to lock the lug cutter in its operative position. The lug cutter is maintained in such position until on the motion of the carriage 61 the projection 53 of the catch 53 strikes against the stop 54, provided on the stationary frame 1, so as to release thev lug cutter, which then falls back into its position of rest after its wire 5() has in a well-known manner cut away to some length the rib on the under side of the stream of clay. For regulating the amount of the forward movement of the carriage the pressure pin 74 is arranged adjustable in a slot 82 provided with a suitable scale 83.
